Infographic design, print design, UI design

Sweden - Last active: 23 hours ago - Tests: 5 - Portfolio: 40

At the core of every successful project lies a good idea. As a designer, I materialize ideas into unique, original design concepts that correspond to the project’s goals, themes and audiences. Be it an infographic, a user interface, a publication or any other format, if its look and feel is defined by its content, it establishes an efficient communication with its target. My professional objective is to present this content in the most lucid, comprehensible way. See examples of my work on my site: http://dalexandrov.com or on Behance: http://www.behance.net/dalexandrov.

Russia - Last active: 23 hours ago - Tests: 9 - Portfolio: 27

Currently I am focused in creating rich client-side apps using JavaScript advanced techniques, CSS3 and HTML5 features. I am keen in creating perfectly looking user interfaces and visualizations with help of D3,js and my great experience with UI/UX. Using best practices and a streamlined workflow I manage to work on complex solutions that include hundreds of user-cases and apps views that are often created as real-time dynamic apps. I use TDD where applicable in my frontend engineering work. Being a problem solver for my clients I am sure that clean, semantic markup and content-driven, responsive layouts are the way forward. I believe in building sites that are device-agnostic, adapting layouts and experiences to a user's viewing environment. I am a fan of progressive enhancement in my work. Having solid backend development experience with multiple languages like Python, C# and JavaScript I try to imagine and see the whole picture of projects I work on.
